That said, do Warlocks have to have evil benefactors? I mean, I don't have the book on me at the moment, so I can't check, but who says that the source of their power has to be evil? Couldn't it just be some powerful non-good entity? Either way, Clerics only have to be within one step of their deity's alignment, so there could very easily be a Chaotic Good Warlock who's the Cleric of a Chaotic Neutral deity. Neutral Deities, since they aren't good or evil (and there's very few powerful neutral outsiders), pretty much have to end up having good AND evil followers. It's quite possible for a Chaotic Good Cleric/Warlock of a Chaotic Neutral deity to have gotten his Warlock powers from one of this deity's evil servants without the Warlock or the Deity being evil.
